How to get more battery life out of Android phones (and tablets)
In the early days of Android it was a real chore to reach the end of a busy day with battery life left. That's improved over time but it can still sometimes be difficult to get through a busy day without running the battery dry. Frequent business travelers in particular know how important it is to stretch the battery, as traveling can be hard on power usage. The tips in this collection can go a long way to help get through those days and safely back to the phone charger.
Many of these tips are simply common sense, but they are worth mentioning just in case. Plus, if they aren't mentioned some will wonder why they were overlooked.
In later versions of Android there is a nice power usage graph as shown above that is accessible via settings. It can help identify culprits that are draining the battery excessively should you notice the remaining battery seems too low.
These tips are specifically for Android phones, but most other phones likely have similar settings that can be tweaked for similar battery gain.
Keep your phone cool
It's not common knowledge but some folks in the know ensure me that letting the phone get too hot can impact the battery life. I'm told the impact on the battery is particularly noticeable at 95 degrees and above so if you live in a hot climate as I do you'd better keep the phone out of the heat.
If it's very hot outside you don't want to be walking in the heat with your phone in hand, as that exposes it directly to the heat. Keep the phone in a bag or a pocket as much as possible to keep the battery from taking a hit.
If you go to a hot place like the beach, don't leave your phone sitting out in the sun as that will surely suck life out of the battery.
Turn down the screen brightness
This is obvious but worth mentioning. The display on Android phones is the biggest drain of battery, so it makes sense to turn it down as low as possible. This can add hours of life to the battery.
Android phones have an auto-brightness setting that automatically adjusts the screen brightness based on ambient room light. This normally works fine but when trying to sqeeze the most up-time on a charge it is worth turning off. Then you set the brightness manually to the lowest setting that is comfortable to still see the screen. It's worth repeating that this can add hours of battery life on a given day.
